What it does

SQL Query Explanation

Overview

This SQL query retrieves data from a table named [Util Selection 0]. It orders the retrieved data based on two columns: [Left$(Right$(" "+[PartNumber],5),4)] and [Right$([partnumber],1)].

Breakdown of the Query

Column Selection

SELECT [Util Selection 0].*

This line selects all columns (*) from the table named [Util Selection 0]. The . notation is used to refer to the current database object, which in this case is a table.

Ordering Clause

The query uses an ordering clause to sort the retrieved data. The sorting criteria are defined as follows:

ORDER BY Left$(Right$("     "+[PartNumber],5),4), Right$([partnumber],1) DESC;

This clause sorts the data based on two columns:

Left$(Right$(" "+[PartNumber],5),4)

This column uses a combination of string manipulation functions to extract and format a part of the [PartNumber] column.
- Right$(" "+[PartNumber],5):
  - Right$: extracts the rightmost characters (up to 5 in this case).
  - The expression " "+[PartNumber] adds leading spaces to the [PartNumber] value. The number of spaces added is hardcoded to 5.
- Left$(... ,4): extracts only the first 4 characters from the result.
This column effectively truncates the [PartNumber] value to a fixed length of 5, with leading spaces if necessary.
Right$([partnumber],1)

This column simply extracts the rightmost character (i.e., the last character) of the [partnumber] column using the Right$ function.

Sorting Order

The sorting order is as follows:

First, the data is sorted by the truncated [PartNumber] value (Left$(... ,4)). The sorting is done in descending order (i.e., from most significant to least significant).
In case of a tie in the [PartNumber] column, the data is further sorted by the last character of the [partnumber] column (Right$([partnumber],1)) in ascending order.

Example Use Case

This query might be used in an inventory management system to quickly retrieve and sort parts based on their part numbers. For example, if you need to find all parts with a specific number of digits at the beginning (e.g., "001", "002"), this query would help you achieve that.
